This invention relates to dust pans, being particularly adaptable for manufacture of a plastic material such as, for instance, Lucite, polystyrene, or other suitable plastic, and aims to provide certain new and useful features of construction and operation whereby the utility and efiiciency of the dust pan are enhanced.

Another object of the invention is the provision of novel features whereby the accumulated dust in the pan ma be disposed of into a waste container in a reduced stream, thereby eliminating the possibility of having any of the matter drop outside the container onto the floor.

The above general as Well as additional and more specific objects will become apparent in the following description, wherein characters of reference refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended for the purpose of illustration only, and that it is neither desired nor intended to limit the scope of the invention necessarily to any or all of the exact details of construction excepting insofar as they may be deemed essential to the invention.

Referring briefly to the drawing, Fig. 1 is a plan view of a dust pan embodying the invention.

Fig. 2 is a side elevational view of the same.

Fig. 3 is a plan view of the dust pan with the pivoted door thereof in opened condition.

Fig. 4 is a sectional view taken on the line 44 of Fig. 3, with the door omitted.

Fig. 5 is a sectional view taken on line 55 of Fig. 1.

The dust pan comprises a substantially S-shaped base 10, having the trough II at the rear, and the crest l2 at the front. The rear Wall I3 rising from the trough II, extends higher than the crest l2, and its upper edge is a straight, fiat surface. On one side a side wall M is provided, whose lower edge conforms to the shape of the base l and whose upper edge lies in the same plane as the upper edge of the rear wall l3. On the other side the side wall comprises two sections, the section being fixed to the base l0 and being similar to the forward portion of the wall l4, and the section l6 which constitutes a door hinged at ll to the section l6 so that, when the door is lifted as shown in Fig. 2, the wall on that side is opened at the trough II.

The door [6 is semi-disc-like in outline, with its curved lower edge circular.

The wall 13 of the base I0, however, is, although arcuate, not- I of the same radius of curvature as the trough, as

since the curved lower edge of the door is of the same degree of curvature as the trough, the rearmost portion of the lower edge of the door would meet the upper inner surface of the wall l3 in closing the door and thereby prevent the curved lower edge of the door from fitting snugly into the trough. To permit of .closing of the door,

is obvious, butrather bends inward. As a'result, 5'6

therefore, a downwardly tapering groove i8 is cut into the said surface of the wall [3, with the rear wall I!) of this groove a continuation of the curve of the trough ll. Thus, when the door is closed, the greater portion of its curved lower edge will register against the surface of the trough II and the rear portion of its lower edge will register in the groove 18 against the inner surface 19 thereof. Thus, when the door is closed, the side walls of the groove 3 serve to prevent sidewise movement of the door.

The upper edge 23 of the door l6, which is straight and also adapted to lie in the same plane as the top of the wall I3 when closed, is provided with a rearward extension or tongue 2| and a slot 22 between the tongue and the door body. When in closed position, the tongue extends through the transverse slot 20 through the wall l3 above the groove wall 19, with the top of the latter registering in the slot 22. The forward edge of the base [0 is beveled, substantially as shown at 24. A handle 25 is provided on the rear wall I3, and it may have a hole 26 therethrough for hanging the pan on a hook or the like.

The entire dust pan, with the exception of the door and its pivot pin, may be molded in a, single piece out of a suitable plastic material, and of course the door [6 would also be made of a single piece of the same material. In use, the pan is held with the beveled edge 24 flush with the floor, and dust is swept onto the pan in the usual manner. To empty the pan, the dust is brought into the trough l I, the pan is tilted to bring the door end of the trough close to the waste container, and the door is opened, whence the dust will fall, or may be swept, out of the pan into the container. In that way there is little likelihood that any of the dust or Waste on the pan will inadvertently be dropped anywhere excepting into the container.

Obviously, modifications in form and structure may be made Without departing from the spirit and scope of the invention.

I claim:

A dust pan comprising a base substantially S-shaped in cross-section thereby providing a trough at the rear and a crest. at the front, the

rear upper portion of said base being deformed in an inward direction with respect to the axis of said trough and constituting the rear wall of the pan, said pan having side walls, one of said side walls having a cut-out therethrough at one end of said trough, a door pivotally secured to said last-named wall andhaving its lower edge curved at a constant radius ofcurvature' equal to the radius of curvature of said trough, said rear wall having a downwardly tapering groove out thereinto, the base of which is a continuation of the circular curvature of said trough, said door when closed having the greater portion of its curved lower edge registering against said trough and the remaining portion of said lower edge adjacent said rear wall registering in said groove.
